Description

Technical Field

[0001] The utility model relates to the technical field of woven bag production, and in particular to a wire drawing machine used for manufacturing environmentally friendly woven bags. Background Art

[0002] Plastic woven bags are mainly composed of polypropylene bags and polyethylene bags. They are divided into seam bottom bags and seam edge bottom bags according to the sewing method. They are currently widely used as a packaging material for items such as fertilizers and chemical products. Their main production process is to use plastic raw materials to extrude films, cut and unidirectionally stretch them into flat wires, and then weave them into warp and weft to get products, which are generally called woven bags. In the wire drawing process, workers need to use wire drawing machines. Although existing wire drawing machines can batch cut woven rectangular strips of raw materials into woven thin strips through wire drawing knife groups, in actual use, workers often need to cut and stretch the woven raw materials into thin strips of different widths according to production needs. At this time, wire drawing knife groups with different densities need to be replaced. However, existing wire drawing knife groups are generally fixed on the wire drawing machine with bolts, so that workers need to use disassembly tools to disassemble and replace the knife groups. This method not only increases the work intensity of the workers, but also affects the overall production efficiency of the woven bags, so it needs to be improved. Utility Model Content

[0053] When it is necessary to adjust the tension of the braided belt during transportation, the staff can start the electric push rod 16, so that the push-pull rod 17 drives the connecting rod 18 to move left or right, so that the lifting rod 14 can drive the tensioning roller 15 to move upward or downward along the outer surface of the guide rod 13, thereby changing the height of the tensioning roller 15, so that the tensioning roller 15 can press or loosen the braided belt, thereby achieving the effect of facilitating the adjustment of the tightness of the braided belt, thereby achieving the effect that braided belts of different widths can be wound and tightened and are not easy to break.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
